Unsweetened cranberry juice has long been associated with urinary tract health, and research suggests that its naturally occurring proanthocyanidins may help prevent certain bacteria from adhering to the walls of the urinary tract, potentially reducing the frequency of infections in some individuals. Studies also indicate that cranberries are rich in polyphenols and antioxidants that may support cardiovascular health, contribute to a balanced gut microbiome, and help inhibit oral bacteria linked to plaque formation and gum disease. Because unsweetened cranberry juice avoids the added sugars found in many commercial blends, it retains more of the fruit's beneficial compounds while minimizing unnecessary caloric intake. As with many functional foods, ongoing research continues to clarify the extent and mechanisms of these potential benefits.
